I just started trying it myself, and it may not be easy for the masters to understand. I hope it will be useful.網(wǎng) Step: 1. Download the phpqrcode.php file in http://phpqrcode.sourceForge.net/, and then put it in your own project;

2, write code and introduce phpqrcode.php files to achieve generating two two seconds to generate two two files to generate two two files to achieve generating two seconds to generate two two two to generate two two files to generate two two files to achieve generating two seconds. QR code.

Code:

1. phpqrcode.php file (download)

2. Test code (erweima.app.php)
